Nodes become singed, especially around the edges, when writes are too
fast.  We have to replace them with fresh nodes, otherwise tasks can't
find the VMAs in that area.

I will have to research how these other people were able to implement
'unsinged' - maybe there's a way to reuse these singed areas more
effectively.
